I'm selling this welder for a good friend of mine.  Its a 2004 Miller Pro 300 with the CAT diesel engine. He is asking $5500 for the welder.  Machine has the silenoid and pc board upgrades. It also has new brushes and a fresh new battery. This welder is exteremly quiet and very fuel efficient.  I have personally ran the machine recently for a couple of days and its an outstanding welder.  My buddy bought the machine brand new in 04 and has loved it ever since. He has built his own shop and is very busy and just doesn't need this big of a machine.  The generator is about 10,000 watts of continous power. You can go to the miller website and get all the specs and fine details.  The machine is located in south central Oklahoma in a town called Duncan, 73533. Thanks
